To all whom #may concern.'

Beit known that I, WILLIAM Marinai., a subject of the King of Roumanie., residing atLos Angeles, in the county of Los Angeles and State of California, have lnvented new and useful Improvements in Attachments for Pencils, of which the following is a ecication.

This device relates to an attachment for pencils arranged for adjustably feeding an eraser, or like article as the latter 1s worn, and decreases in length.

\ It is an object of this invention to provide. an attachment having' a" barrel for calrryin a calendar Aor other display sheet and wit in which is disposed a structure-for ad'ustably feeding an eraser.

lt is anothr object to provide details of construction whereby a compact feeding structure is obtained and whereby the eraser or like article may be quickly and conveniently renewed. l

It is a further object to provide an attachment for a pencil, having a pocket retaining means to prevent loss of the pencil, a calendar and an eraser holder which is. compact, light, easily Lattached and pleasing in ap- I accom lish these objects `by means of 80 the embodlment of my invention illustrated inthe accompanying drawing, in which:

Figure 1 is an elevation of the pencil with my attachment applied thereto.

Fig. 2 is an `enlarged vertical section V36 through the attachment,asv seen on theline 2-.2of Fig. 1, the eraser being shown in its innermost position.

Fig. 3 is a Vfragmentary sectional view similar to Fig. 2 showing the eraser proi 4o jected'. t

Fig. 4-is a section as seen on the line 4 4 Figo 5 is a section as seen on the line 5-5 Fig. 6 is asection as seen on the line 6-6 0f Fl 2, v

As 1t will be noted from an inspection of Fi 1, the attachment AY is placed on the en 4of apencil B in the manner in which the ordinary pocket clips are placed upon the pencils. The attachment A is comprlsed of -a shell Vhaving a sleeve- 7 for engagement y with-the pencil B, and=an enlarged barrel to receivefalcalendar. The barel is of tubu- 55 lar forn'jand is provided with cut out vportions openingsforgthe display of calendars. The barrel, therefore, comprises an upper cylindrical ring 8 and a lower ring 9 joined by columns, which are indicated by 10... The upper ring 8 is split as shown in Fig. 5 so that it is expansible.

The sleeve 7 is split longitudinally, as indicated by 11 and 1s provided with. an intersecting slit 12 thereby providing' spring in gers for gripping the end of the encil. Secured to sleeve 7 and preferably integral therewith isa de ending clip 13 having a ball 14 at the endJthereof.' The clip is for the purpose of securing the pencil in the pocket and retaining it against loss.

Secured to the shell and disposed within the calendar barrel is a post 15. Post-15 is hexagonal in cross section for the purpose of providing flat sides.

Ring 9 has an off-set formed therein as indicated in Fig. 2 to provide a rabbet in which a calendar sheet indicated by the dotted lines may be disposed. The upper ring 8 is indented to provide a rabbet and also has an indentation to receive a raised portion on the interior of a cap. The post 10 is also indented to provide rabbets. The structure' of the barrel is such that calendar sheets, preferably inclosed in a trans arent sti'i'l material, such as celluloid, may e disposed in the openings between the columns. The rabbets Vwill prevent rotation of the calendars. Any other display sheet may be used instead of a calendar.

, Mounted upon post 15 is an eraser holder consisting of a 'sleeve 16 having a hexagonal bore to prevent rotation, and having eX- ternal threads upon the lower end of its periphery. The upper end is reduced in diameter and slit to provide gripping jaws for enga ing and retaining an eraser 17. `It will e noted that the eraser may be slipped between'the jaws and removed `by pulling it therefrom. The jaws bite the eraser with suflicient force to hold it in place for, the

ordinary strainV to which it is subjected in erasing. A

Mounted upon the barrel is a cap. The cap is comprised of a cover 18 having a neck through which the eraser may be projected. An apron 19 overhangs the rin ,8;

apron-is provided with a raised ri 20 on its mterior which engages with the indentation in the ring 8. -Itis obvious that by pressing the cap 18 into 'place and` contracting the ring 8 bypressing upon the same, the cap will reach its locking position, and upon'rewill expand the indentation and rili'locking to j irevent the displacement ol the cap from the barrel. 'l`o reiiiovethe cap the ring 8 is conti-acted, pressing upon. the columns l() will cause contraction of the ring. The 'Cup may then he aithdi'auu troni the barrel.

Depending from .ie rover is a sleeve. 21.

Sleeve 2l is provided internally with threads at its lower end which engage with the threads cin-holder 1G. Tt is obvious that the eapinay he rotated upon'th'e barrel vand that the rotation of tht` cap sleeve 21 ivill force the holder ilt iipivardljY or downwardly at livill as the liold'er cannot rotate,iheiiig held in position b v the post l5. The holder is, thus, projected and the eraser forced through the cover. The holder and eraser iii their Lipper position are shown in Fig. 3.

In order to pirdvide convenient gripping means to rotate the cap, the outer surface oi the apron is knurled. The pencil B may be forced into. the attachment with the up per end thereof extending ii-'itliinthepost therehy providing for secure attachment to the pencil. l
